Definitions
- This invention relates to biologically active vitamin D 3 compounds. More specifically, the invention relates to 19-nor-analogs of l ⁇ -hydroxylated vitamin D 3 compounds having calcemic activity.
- Such analogs are l ⁇ - hydroxyvitamin D 3 , l ⁇ -hydroxy vitamin D 2 , various side chain fluorinated derivatives of l ⁇ ,25-dihydroxy vitamin D 3 , and side chain homologated analogs.
- Several of these known compounds exhibit highly potent activity in vivo or in vitro, and some of these have been found to exhibit an interesting separation of activities in cell differentiation and calcium regulation. This difference in activity provides these compounds with advantageous therapeutic activity profiles and thus numerous of these compounds are in use, or have been proposed for use, in the treatment of a variety of diseases such as renal osteodystrophy, vitamin D-resistant rickets, osteoporosis, psoriasis, and certain malignancies.
- 19-Nor- vitamin D compounds are vitamin D analogs in which the ring A exocyclic methylene group (carbon 19) typical of all vitamin D compounds has been removed and replaced by two hydrogen atoms. Specifically, these compounds were reported to exhibit a selective activity profile with high potency in inducing cellular differentiation, and minimal bone calcification activity. See U.S. Patent 5,587,497. Such a differential activity profile renders these compounds useful for the treatment of malignancies, or the treatment of various skin disorders such as psoriasis.
- Fig. 1 is a graph of the percent differentiation of HL-60 cells versus concentration of l ⁇ ,25-(OH) 2 D 3 as compared to 19-nor-26,27-dimethyl-22,23(E)-l ⁇ ,25-(OH) 2 D 3 ; and Fig. 2 is a graph of the competitive binding ability versus concentration for the same two compounds as in Fig. 1.

- 19-nor- vitamin D compounds having the structure shown above can be accomplished by any of several different common general methods using known starting materials. Suitable methods are illustrated and described in U.S. Patents 5,587,497; 5,281,731; 5,086,191; 4,851,401; and 4,847,012, the descriptions of which are specifically incorporated herein by reference.
- Biological Activity of l ⁇ -Hydroxy-19-Nor-26 and/or 27 Homologated Vitamin D Compounds exhibit an unexpected pattern of biological activity.
- 19-nor-26,27-dimethyl-l ⁇ ,25-dihydroxy-22,23(E)-dehydrovitamin D 3 exhibited high binding activity to the porcine intestinal vitamin D receptor, and high potency in promoting the differentiation of malignant cells. These two activities were essentially equivalent to the natural hormone l ⁇ ,25-(OH) 2 D 3 (See Figs. 1 and 2).
- Fig. 1 shows a comparison of the activity of the known active metabolite l ⁇ ,25- dihydroxyvitamin D 3 and the 19-nor-26,27-dimemyl-22,23( ⁇ )-dehydrovitamin D 3 analog in inducing the differentiation of human leukemia cells (HL-60 cells) in culture to normal cells (monocytes).
- HL-60 cells human leukemia cells
- NBT nitrogen blue tetrazolium reduction
- the assay was conducted according to known procedures, as given, for example, by DeLuca et al U. S. Patent 4,717,721 and Ostrem et al, J. Biol. Chem. 262, 14164, 1987.
- the differentiation activity of the test compounds is expressed in terms of the percent of HL-60 cells having differentiated to normal cells in response to a given concentration of test compound.
- Fig. 1 The results summarized in Fig. 1 clearly show that the 19-nor-26,27-dimethyl- 22,23 (E)-dehydrovitamin D 3 analog is as potent as l ⁇ ,25-dihydroxyvitamin D 3 in promoting the differentiation of leukemia cells.
- NBT assay close to 90% of the cells are induced to differentiation by l ⁇ ,25-dihydroxyvitamin D 3 at a concentration of 1 x 10 "7 molar, and the same degree of differentiation is achieved by the 19-nor analog.
- Fig. 2 shows a comparison of the same two compounds as in Fig. 1 illustrating their relative activity with regard to competitive binding to the vitamin D receptor.
- the competitive receptor binding was done with pig nuclear extract as described in Perlman et al. Biochemistry 29, 190-196 (1990) using the porcine extract prepared as described by Dame et al PNAS 82, 7825-7829 (1985). These data are used to demonstrate that the compounds described herein have relatively high in vivo activity, and have somewhat less activity than l,25-(OH) 2 D 3 in binding to the vitamin D receptor.
- EXAMPLE 2 The biological data on the calcemic activity of the compound 19-nor-26,27-dimethyl- l ⁇ ,25-(OH) 2 D 3 is reported in Table 1.
- Table 1 The biological data on the calcemic activity of the compound 19-nor-26,27-dimethyl- l ⁇ ,25-(OH) 2 D 3 is reported in Table 1.
- Holtzmann weanling rats were maintained on a low Ca diet (0.02% Ca, 0.3% P) for three weeks. During the 4th week all animals were dosed with the appropriate compounds via the peritonal cavity. All doses were suspended in ethanol propylene glycol (5/95) and administered daily for seven days. None of the compounds produced hypercalcemia over the seven day dosing period.
- 26,27-dimemyl-l ⁇ ,25-dmydroxyvitamin D 3 compound has an activity profile similar to 1,25- (OH) 2 D 3 but has preferential activity on bone. TABLE 1
- This experiment was carried out with 8-month-old female rats purchased from Sprague-Dawley Company. 88 of the 100 rats were ovariectomized; the other 12 were sham operated. They were fed the Purina Rat Chow diet 5012 ad libitum and distilled water throughout the entire experiment. The sham-operated and ovariectomized rats were allowed to proceed with monitoring by the DPX ⁇ of Lunar Corporation that measures whole animal bone mineral density. It took 5 months of depletion before significant difference could be found in bone mineral density of the ovariectomized versus sham- operated controls.
- the sham-operated controls were allowed to continue as before, while the ovariectomized animals were divided into groups of 12 animals per group. They were given the indicated doses for a period of 7 months. Bone densities were measured at 7 months, at 10 months, and at 12 months. The animals were sacrificed at that point, femurs were removed to determine total and percent ash, and plasma was taken for the determination of serum calcium concentration. The results are provided as the mean ⁇ standard error of the means for 12 animals. Bone density was determined by dual photon absorptiometry as indicated from the manual for the DPX ⁇ instrument of Lunar Corporation. There is also a reference to the calculations that are made from the absorption of photons by the skeleton. This is supplemented with the chemical determination of the ash content in mg. Percent ash is also reported to indicate that there was no osteomalacia but rather only osteoporosis was being treated.
- the above 19-nor compounds thus exhibit a desired, and highly advantageous, pattern of biological activity.
- These compounds are characterized by relatively high intestinal calcium transport activity, but less than that of l ⁇ ,25-dihydroxyvitamin D 3 , while also exhibiting much higher bone calcium mobilizing activity.
- these compounds are highly specific in their calcemic activity.
- Their preferential activity on mobilizing calcium from bone and intestinal calcium transport activity allows the in vivo administration of these compounds for the treatment of metabolic bone diseases where bone loss is a major concern.
- these compounds would be preferred therapeutic agents for the treatment of diseases where bone formation is desired, such as osteoporosis, especially low bone turnover osteoporosis, steroid induced osteoporosis, senile osteoporosis or postmenopausal osteoporosis, as well as osteomalacia and renal osteodystrophy.
- the treatment may be transdermal, oral, sublingual, intranasal or parenteral.
- the compounds may be present in a composition in an amount from about O.l ⁇ g/gm to about 50 ⁇ g/gm of the composition, and may be administered in dosages of from about O.l ⁇ g/day to about 50 ⁇ g/day.
- the compounds of the invention are also especially suited for treatment and prophylaxis of human disorders which are characterized by an imbalance in the immune system, e.g. in autoimmune diseases, including multiple sclerosis, diabetes mellitus, host versus graft reaction, and rejection of transplants; and additionally for the treatment of inflammatory diseases, such as rheumatoid arthritis and asthma, as well as the improvement of bone fracture healing and improved bone grafts.
